Rura: Interactive TUI scratchpad for building shell pipelines

Rura is a new open-source command-line tool (written in Rust) that provides an interactive TUI (terminal user interface) for building shell pipelines. Instead of typing a long one-liner with pipes (|) and hoping it works, users can visually construct a pipeline by selecting commands, editing their arguments in separate panes, and seeing intermediate output at each stage. The project is on GitHub under tlipinski/rura. It fills a gap for users who find traditional shell pipelines powerful but error-prone and hard to debug — especially when dealing with complex text-processing chains involving tools like grep, sed, awk, sort, jq, and others. The name combines "Rust" and possibly "ura" (from Japanese 裏, "reverse/rear") or is simply a play on "rural" — the README is not explicit.
